I bought the Koki paste from the same shop in Poland, and i must say the transaction was quick, and secure. I recomend the shop highly. Looks like theres not many dealers around europe at the moment, so the choices are limited.
The price is high, but on the good side- the tub of Koki paste will last for years- providing we never forget to put the paste in the fridge after use. It states on the packaging, that the life of the paste is aprox. 6 months, but i had mine since 2007, and is still as good as new, and still about 3/4 of the tub left. Good stuff honestly.
Meanwhile i have finished sculpting the pigeon.
Wings, and tail from beer can, legs made using 0,150mm copper wire, and the rest is Green Stuff.
